LoginManager & Session Tracking Status
by Gerald Gutierrez 06 Mar '01

06 Mar '01

Hi all. I understand that the current LoginManager will work with Zope 2.3.0 with some small tweaks with the source code. If they are indeed small tweaks, can I expect a new version of the LoginManager, which works out of the box with Zope 2.3.0, to be released soon? Also, both the LoginManager and Core Session Tracking seem to be indispensable features for application servers. Is there any indication when they will be rolled into Zope?

FrontPage Extensions incompatible with Zope?
by Fred Yankowski 06 Mar '01

06 Mar '01

I run a simple Zope-based web site for my local community, and I'm having trouble supporting authors who want to use FrontPage. Is there any good way to use FrontPage with Zope? This seems an obvious FAQ, but I found little help after a long search. There are at least three categories of trouble using FrontPage with Zope, that I know of: 1) FrontPage generates files and folders whose names start with "_", thereby breaking a cardinal Zope naming rule and causing those files and folders to be inaccessible (if done via LocalFS) or outright impossible (in Zope proper/ZODB). 2) FrontPage uses custom HTTP-based RPCs to do file upload and administration. I know next to nothing about this, but I'm pretty sure that Zope does not support this extended HTTP protocol directly. Seems like it could though. 3) FrontPage uses its own library of server-based features, such as for counters. I don't even own a copy of FrontPage, much less have any practical experience with it, so I'm flying blind here. But this _has_ to be a common problem, right? How have you solved the problem? (Answers along the line, "Don't use/allow FrontPage", are not useful to me.) For those who care about this problem, here's a bit more detail: The website in question is hosted on an NT4 server, so I've got IIS available. I run Apache on port 80, IIS on 82, and Zserver on 8080. Most stuff for the site is ProxyPass'ed from Apache to Zope. But I'm now intercepting the FrontPage-based stuff in Apache and ProxyPass'ing it to IIS. I gave the FrontPage-using developer the IIS URL to upload her work, which is then stored as regular files/folders in NT. I can use LocalFS in Zope to access that content, but the leading underscores in file/folder names cause trouble and the server support for FrontPage extension features like counters doesn't work, and I can't see how to make it work from Zope. -- Fred Yankowski fred(a)OntoSys.com tel: +1.630.879.1312 Principal Consultant www.OntoSys.com fax: +1.630.879.1370 OntoSys, Inc 38W242 Deerpath Rd, Batavia, IL 60510, USA

What exactly is the problem that you're having with namespace binding, and why would you want it in a Script that's used as the target of a URL? Cheers, Evan @ digicool & 4-am

Minor Tab bug?
by complaw＠hal-pc.org 05 Mar '01

05 Mar '01

This isn't a showstopper, and if someone else has pointed it out, please disregard. However, I found a minor bug in Zope 2.3.0. Here it is. When you are using the management screent to edit the properties of a folder, once you press the "Save Changes" button, the changes are indeed changed, and the content of the "Properties" tab is indeed shown, but the tab itself that is indicated is the "Contents" tab, rather than the "Properties" tag. Its not a big deal, and is easily worked around. For that reason, I don't know if anyone bothered to mention it. If there is a bug tracking list, please direct me to it and I'll add it there (but it wasn't obvious from the Zope site that there was a specific bug-tracking list). Cheers, Ron

Newbie: help with Zope Book script error
by Robert H. Boyd 05 Mar '01

05 Mar '01

Greetings, I'm not having success with the Zope Book ch 3 script example. First, I've noticed it has the formula wrong in the script. Original: i = interest_rate * periods # (don't I wish my bank would do this :) i = i + 1 n = periods * years return pow((1 + i), n) * principal # already added 1 to i above Correct: i = interest_rate / periods i = i + 1 n = periods * years return pow(i, n) * principal BUT, even with that, submitting the form returns an error of "not enough arguments: expected four, got 0". In the Zope manager, on the editor for script calculateCompoundingInterest, I have entered principal, interest_rate, periods, years in the parameters field. The form page has these same params specified as input fields; I don't know much about Zope but I'd guess that Zope should understand that each named input field is a parameter name, accompanied by its value. So what is going wrong? Does the script itself need to look more like a regular Python function, ala 'def calculateCompoundingInterest(principal, interest_rate, periods, years):' ? Or is <dtml-var calculateCompoundingInterest> not the correct way to call a script from a page? TIA, Robert Boyd

LocalFS and html quoting
by Ron Bickers 05 Mar '01

05 Mar '01

I'm trying to include a specific LocalFS file into a dtml document, but it is getting html quoted. Also, it seems that Jonothan Farr's how-to is either wrong, or I don't know what I'm doing. Including the contents with the 'data' property does not work (I get an attribute error). My LocalFS object is called lfs, and I'm including the contents using the following (where string Filename contains the file name in the articles subdirectory): <dtml-in "lfs['articles'].fileValues(Filename)"> <dtml-var getObject> </dtml-in> I've tried sequence-item (which just gives me the Local File object instance), and various other things (including just plain <dtml-var lfs['articles']['thefile.html']">, but it's always quoted. Any hints on getting it included without html quoting? Thanks! _______________________ Ron Bickers Logic Etc, Inc. rbickers(a)logicetc.com

"sendmail" is very sensitive to leading white space. The mail headers ("To:", "From:" etc) must all start in the first column. Dieter

When you know, how to do something with JavaScript, you always can use "hidden form controls" or query strings to pass the information to Zope (or any other HTTP server). Dieter

Zope implements HTTP 1.1 only to a small extend. If you have programming skills, you could enhance the "OFS.Image.File.index_html" method to support partial loads. Dieter
